Problems solved by technology

[0004] The problem with the real-time query solution is that once the amount of query data sent is large, it will take a lot of searching, statistics or calculations in computing device B to get the query results, making computing device A wait for a long time
However, there is a disadvantage that computing device B can only obtain query results based on fixed queries, and cannot satisfy all query conditions of computing device A, so that real-time query is still required for some queries
At the same time, some unused or seldom-used queries are also periodically searched, and the corresponding query results are stored, resulting in a waste of computing resources and storage resources

Abstract

The invention provides a method and apparatus for executing data query. The method comprises the following steps: receiving a query from a query requester; determining whether a query result data setcomprises a query result corresponding to the query, wherein the query result data set comprises one or more query results corresponding one or more previous queried obtained from a database system; in response to the determination that the query result data set comprises the query result corresponding to the query, sending the query result to the query requester; and in response to the determination that the query result data set does not comprise the query result corresponding to the query, adding the query to a query data set, wherein the query data set comprises one or more queries to be executed in the database system.

Description

technical field [0001] The present invention relates to the computer field, in particular to a method, device, electronic equipment and storage medium for executing data query. Background technique [0002] In a real computing environment, computing devices usually need to interact frequently to obtain required data. For example, query requester computing device A sends a query to query recipient computing device B requesting query results. There are two commonly used schemes at present. One scheme is real-time query, that is, the computing device B immediately searches for the query result after receiving the query from the computing device A. Another solution is to periodically obtain query results in computing device B based on a fixed query, store the query results in the data storage module of computing device B, and wait for queries from other computing devices. [0003] In the course of realizing the present invention, the inventor finds that there are at least the ...
